pub enum ServiceInvocationError {
    AlreadyExists(String),
    DeadlineExceeded,

    InvalidArgument(String),
    NotFound(String),

}

An error indicating a problem with invoking a (remote) service operation.

Variants

AlreadyExists(String)

Indicates that the calling uE requested to add/create something that already exists.

DeadlineExceeded

Indicates that a request’s time-to-live (TTL) has expired.

Note that this only means that the reply to the request has not been received in time. The request may still have been processed by the (remote) service provider.

FailedPrecondition(String)

Indicates that the service provider is in a state that prevents it from handling the request.

Internal(String)

Indicates that a serious but unspecified internal error has occurred while sending/processing the request.

InvalidArgument(String)

Indicates that the request cannot be processed because some of its parameters are invalid, e.g. not properly formatted.

NotFound(String)

Indicates that the requested entity was not found.

PermissionDenied(String)

Indicates that the calling uE is authenticated but does not have the required authority to invoke the method.

ResourceExhausted(String)

Indicates that some of the resources required for processing the request have been exhausted, e.g. disk space, number of API calls.

RpcError(UStatus)

Indicates an unspecific error that occurred at the Transport Layer while trying to publish a message.

Unauthenticated

Indicates that the calling uE could not be authenticated properly.

Unavailable(String)

Indicates that some of the resources required for processing the request are currently unavailable.

Unimplemented(String)

Indicates that part or all of the invoked operation has not been implemented yet.

Trait Implementations

impl Clone for ServiceInvocationError

fn clone(&self) -> ServiceInvocationError

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ServiceInvocationError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ServiceInvocationError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ServiceInvocationError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<ServiceInvocationError> for UStatus

fn from(value: ServiceInvocationError) -> Self

Converts to this type from the input type.

impl From<UStatus> for ServiceInvocationError

fn from(value: UStatus) -> Self

Converts to this type from the input type.
